Flashing ESP from another ESP or MCU?

Hello friends,
I want to flash ESP8266 from another ESP8266 or Arduino instead of a PC. This is for mass-flashing a number of ESPs with same firmware.
Has anybody done something like it?
Or if anybody is interested, we can co-develop it.

I just registered to ask the very same thing.
I have an ESP module with 5V->3.3V regulator and a USB<->UART easily programmable from my computer (not a NODEMCU but similar), and I would like to use that component to bootstrap a bare bone ESP8266 module with no such convenient features. It is not a price issue, but size (the convenient version is 3x the size of the bare bone ESP8266) and power usage (no USB<->UART chip neither power leds).
This is something I can do even bit-banging an UART to the second ESP and implementing the flash programming protocol, but I guess that somebody else has already do this. But I am unable to find anything relevant.
Thanks!

Maybe someone with in depth knowledge about the serial protocol for programming the ESP8266 should chat about it and where to find the exact files that outlines the protocol....
